The difference between guilt and shame is guilt is something you feel about an action you take and shame is feeling like you are the mistake. The only fatal mistake we can make is to feel shame. We all do and say things that we regret but once you let you mistakes and guilt color everything you identify yourself as, you can't get better. I hope you find some peace and learn to forgive yourself for what you feel is bad about you. I hope you learn to take time to rest and truly rest. Not feel guilty/shameful about needing some time to recover or asking for help, because if you are fighting guilt when you are trying to rest you are not recovering physically or psychologically. I hope you peace and balance.
